There's threads here too. My wiring is different. Feel free to ask after you've done some reading up on the subject--

Have fun.

EDIT: The first thing I'd do is get a real water temp gauge. That way you know what is going on at all times. Individual preferences vary- but I use a full-sweep Autometer ES. Accurate, nice looking, and matches BMW illumination. Pricey, but worth it to me.
